Mandy is making a rectangular quilt. She created a scale drawing of the quilt using a scale of 1 cm = 7.5 in. The quilt on the drawing measures 8 cm by 12 cm. What is the area of the actual quilt?

Respuesta :

Answer:

Actual Area=5,400 (in.)²

Step-by-step explanation:

Scale: 1 cm=7.5 in.

Drawing is 8 cm by 12 cm

Drawing Length=12 cm

Actual Length=Scale factorĂ—Drawing Length=(7.5Ă—12)=90 in.

Drawing Width=8 cm

Actual Width=Scale factorĂ—Drawing Length=(7.5Ă—8)=60 in.

Actual Area=(Actual LengthĂ—Actual width)=(90Ă—60)=5,400 squared inches

Actual Area=5,400 (in.)²
